RAILROAD ROLLING-STOCK RERAlLlNG DEVICE ANDABRIDGE-GUARD FOR SAFETY.

SPECIFICATION forming part of Letters Patent No. 410,222, dated September 3, 1889.

n Application filed May 1, 1889. Serial No. 309,303. (No model.)

T0 all whom it may concern:

Be it known that I, BURT E. TILDEN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga. andState of Ohio, have invented certain new and useful Improvements in Railroad Rolling-Stock Rerailing Devices and Bridge-Guards for Safety, of which the following is a specification.

My invention relates to improvements in devices for replacing upon the track rollingstockwhichbecomes derailed, and is particularly designed to be applied to the approaches to railroad-brdges or other points upon a railroad wh ere it is desired to replace upon the rails rolling-stock that may become derailed.

The objects of myinvention are to provide a rerailing device which will offer no obstruction to rolling-stock while passing over the track, and which will be durable and effectual inaction and able to withstand the most severe strain .in replacing rolling-stock.

My invention is illustrated in the accompanying drawings, in which- Figure l is a vertical transverse section through the lines Qc x of Fig. 2. Fig. 2 is a plan view of the rerailing device. Fig. 3 is a vertical transverse section showing the bearing of awheel upon the rerailing-frog B. Fig. 4. is a perspective view showing the rerailing device in detail and its operation in rerailing.

In the accompanying drawings, A A represent the rails of a railway, and A A repre` sent guard-rails. Outside of each rail A is placed a rerailing-frog B, the two frogs being placed opposite to each other and being attached to the railroad-ties in any suitable manner.` Each rerailing-frog B is constructed with a illing F, of wood or any other suitable material, over which is placed a plate C, which is inclined toward the rail A, and is fastened to the filling and also to the ties by spikes or other suitable means. surface of the frog B is inclined toward the rail A. The curved bearing-surface of the frog B is shorter next to the rail than at its greatest distance from the rail, and the bearing-surface of the frog at t-he ends is inclined toward the rail, as shown, so that a wheel striking the frog will ascend the frog bearing upon its tread rather than its iiange, as isshown in Figs. l and 3. The top of each frog The upper 0r bearing .B is of such a height that a` wheel passing over it will be lifted high enough to allowthe Each frog B is inclined longitudinally at each end to the level of the ties, thus rendering the frog suitable to be .used for either rail and 6o making it operative at either end. At its greatest height each frog B is extended longitudinally a sulhcient distance to allow a wheel upon it to be eifectually drawn onto the rail by the opposite guardrail or by gravitation. I prefer to make the longitudinalA extension of the highest part of the frog B equal to about one-third of the length of the frog; but the length of the'upper longitudinal eX- tension of the frog is not material in my in- 7oV vention. The rerailing-frog B maybe made solid or a metallic shell and of any suitable material; but Iprefer to make it asshown and described, a frog constructed in this manner being cheaper than a frog constructed of solid metal and of equal durability. It is not essential to myinvention that the frog B be set into the cross-ties, as shown in the drawings. Each rerailing-frog B is placed at a sufficient distance away from its corresponding rail A to So allow the wheels of rolling-stock to pass over the rails free and clear of the frog., Between the rails A A are placed the guard-rails A A',

which converge from a point opposite the frogs B B to the center of the track, and in 8x5 the opposite direction may extend parallel with the rails A A, as shown in Fig. 4, or be turned in, as shown in Fig. 2. Each rerailing-frog B, with corresponding guard-rail A',

is held firmly in position by means of a plate 9o D, which passes under the guard-rail A and rail A, and passes under the surface-plate C of the frog B, and is fastened to the tie at either end by spikes or other suitable means.

The plate D should be set into the tie sufi- 9 5 ciently to allow rails A and A to rest upon the tie, and is provided with an elevation upon the inside of the guard-rail A and thev vout-side of the rail A, whichserves to hold the guard-rail firmly in position to the rail A. 10o

The plate D may be fastened to the tie between the guard-rail A and rail A by means a metal iller or lifter E. The rails A and A are also held in position by a bolt G, which passes through rails A and A' and through the metal lifter E. rlhus the guard-rail'and rerailing-frog B are always held iirnily in the same relative position tothe rail A.

The operation of my device in rerailing rolling-stock will be understood from the above description. Vhen a truck leaves the track, its Wheels come in contact With a guardrail A', and are guided to a position close to the rails A A, where the Wheels inside of t-he track are raised by the lifter E to a height sufficient to be crowded onto the track by the adjacent guard-rail A', and the Wheels outside of the track atthe same time pass up the frog B and are lifted to a height sufficient to allow the iiange of the 'Wheel to pass over the rail and the Wheel to be drawn onto the rail by the opposite guard-rail A or by gravitation.

In rerailing rollingstock it has been cus` tolnary to attach outside of each rail a frog contiguous to the top of the rail upon which the Wheel ascends on its ange to the level of the upper surface of the rail, and from there is shifted to its position upon the rail entirely by the action of the opposite guardrail. Obviously the frog thus placed can be raised to no greater height than the top of the rail, as it would form an obstruction to the Wheels of passing trucks. If raised to the level of the upper surface of the rail, the constant passing of heavy trains causes the rail to depress, and the tread of passing Wheels, especially of those Wheels Whose bearingsurface has been Wornhollow next to the iian ge, then Wears away the rerailing-frog. In

case of derailrnent the Weight of the car is shifted to the frog, which causes it to depress and the rail to raise, and the frog by reason of the wear described the-n becomes inoperative in rerailing. In my device the rerailing-frog is placed free and clear of the rail and at such a distance from the rail that it can neverbe injured by passing Wheels, and at the same time it is of sufficient height above the rail to lift the flange of the Wheel onto the rail in case of derailment, as has been illustrated.

Vhat I claim, and desire to secure by Letters Patent, is-

I. In a rerailing device, the rerailing-frog B, being placed clear of the rail A, having its bearing-surface inclined toward the rail, as herein described, and having its upper bearing-surface higher than the top of the rail, substantially as and for the purposes described.

2. In a rerailing device, the combination of the rerailing-frog B, placed clear of the rail and inclined, as herein described, with railA and guard-rails A' A', substantially as and for the purposes described.

3. In a rerailing device, the combination of the frog B with the fastening-plate D and rails A and A' A', substantially as and for the purposes described.

4. In a rerailing device, the combination of the rerailing-frog B with the plate D, rails A and A', lifter E, and bolt G, substantially as shown, and for the purposes described.
